Application filed m 'aa,

My invention relates to electrical connectors and more particularly to aplug for attaching an electric cord to a socket.

The object of the invention is to provide a connecting plug havingabutments, for assistingin supporting the plug when it is connected intoa socket in a horizontal position, and a'handle by means of which theplug may be inserted in a socket and withdrawn therefrom, thus tendingto overcome the usual practice of removing a plug from its socket byjerking on'the electric cord.

' With this and other objects in view, the invention resides in thefeatures of construction and arrangement of parts herein deing screws 10for securing the ends of the ,wires of an electric cord 11 which entersrecess 6 through an insulating bushing 12.

That part of recess 6 not occupied by block 7 is preferably lined withan insulating ring 13 and an insulating disk 14, through whichinsulating bushing 12 extends. The rear wall of shell 5 preferablyslopes outwardly and forwardly from its median line so that cord 11 mayextend rearwardly at an angle from the shell without interfering with ahandle 15 secured to or formed on shell 5 parallel to its center line.

In order to assist prongs 9 in supporting the block when it is insertedhorlzontally into a socket, abutments 16 are secured to or formed on theshell in alignment with handle 15 and with their front .ends flush withor ex- Even when the prongs fit loosely in a horizontally disposedsocket the lower abutment supports the plug in a horizontal position;

two abutments being provided so that the plug may be inserted in asocket with either side up. When an electric cord is equipped with oneof these plugs, it is found that there 1s little tendency upon the partof the user to remove the plug from the socket by jerking upon the cord,as the shape of handle 15 inembodiment of my invention, it will beunderstood that modifications may be made without departing fromthe-spirit thereof and, hence,

I do not wish to limit myself to the precise 6 construction set forthbut consider that I am at liberty to make such changes and alterationsas fairly come 'within the scope of the appended claims.

I claim 1. A connecting plug including a shell, an nsulating blocksecured in the shell, connecting prongs extending through the block,means for securing anelectric cord to, the prongs, a handle formed onthe shell, and an abutment formed on the shell substantially flush withthe front end thereof.

2. A connecting plug including a shell, an apertured handle formed onthe shell, an in-. sulating block-secured in the shell, connectingprongs extending through the block, an insulating bushing extending intothe shell adjacent the handle for accommodating an electric cord to beconnected to the prongs, and abutments formed on the shell substantiallyflush with the front end thereof.

3. A connecting plug including a shell haV- ing a recess, an insulatingblock secured in the recess flush with the front end of the shell,prongs extending through the block, binding screws on the prongs, aninsulating bushing extending into the recess at an angle to the axis ofthe plug, a loop-shaped handle formed on th shell adjacent the bushing,and abutment formed on the shell substantially flush 95 with the frontend thereof.

In testimony whereof I have signed my name to this specification.
